Section B: Public Involvement and Participation
B.1 Program Narrative
The City provides several opportunities for public involvement and participation. The
City’s Stormwater Management Plan is noticed and presented at a public hearing for
comment by the public once per permit cycle. New regulations associated with
implementing the plan are noticed and presented at a public hearing prior to adoption.
The annual budget for the Stormwater Management Division is noticed and presented for
public comment prior to adoption. As a means of obtaining more regular public input on
policy and project related matters, the City Council established the Stormwater
Management Advisory Commission (SMAC) that reviews stormwater management
issues and provides guidance and recommendations to Council. SMAC is composed of
ten citizens from diverse backgrounds, including the business community, environmental
groups, engineers, homeowners, and the public. Monthly meetings of SMAC are open to
the public, and public input is invited.
B.2 Best Management Practices
B.2.1 Administer a Public Involvement Program
The City provides a number of public involvement opportunities annually and at
the time of revising the Stormwater Management Plan. These opportunities are
described below.
B.2.2 Allow the public an opportunity to comment on the Stormwater Plan
The Stormwater Plan is revised with each permit cycle and is presented to City
Council for public hearing. The current Stormwater Management Plan, which was
updated May 2015 and available for public comment June 2015, is available to
the public upon request.
B.2.3 Organize a volunteer community involvement program
The City’s Stormwater Management Division sponsors four volunteer programs
including Adopt-A-Stream, Foster-A-Stream, Storm Drain Marking, and
Volunteer Stream Monitoring. These volunteer programs are maintained
throughout the year with ongoing volunteer activities, including two Foster-A-
Stream events organized by City staff and two Volunteer Stream Monitoring
workshops. Information is provided at

B.2.4 Establish a Mechanism for Public Involvement
SMAC was established in 2003 by a resolution adopted by City Council. It is the
official citizen advisory board to City Council on issues pertaining to stormwater
program policies. SMAC advises Council and staff on matters pertaining to
policy changes and stormwater services and reviews the annual stormwater
budget and capital improvement plan. It consists of ten members residing within
the Raleigh City limits appointed by City Council to overlapping two-year terms.
SMAC’s monthly meetings are open to the public. SMAC’s mission statement is:
SMAC will manage resources sufficiently to protect the public infrastructure,
quality of life, environment, and property of the citizens of Raleigh through fair
and equitable cost-effective means. SMAC’s recommendations will seek to
improve, enhance, and protect the quality of the Neuse River. Information is
provided at
http://www.raleighnc.gov/home/content/BoardsCommissions/Articles/Stormwater
ManagementAdCommission.html.
B.2.5 Establish Hotline/Helpline
The City utilizes the Stormwater Management Division’s main telephone line,
(919) 996-3940, as a helpline. In 2016 the Stormwater Management Division
initiated use of a dedicated email address, IllegalDischarge@raleighnc.gov, as
another helpline for citizens.
These helplines are maintained during working business hours. After hours and on
weekends, calls regarding spills and other illicit discharges are received by the
City’s 911 center and routed to the Fire Department or other appropriate
department, depending on the nature and urgency of the spill or discharge.
During this reporting period, approximately 80 water quality-related calls were
received from citizens, with 24 of these calls originating from the dedicated water
quality helpline and email.

Section C: Illicit Discharge Detection and Elimination
C.1 Program Narrative
The City has had an illicit discharge program since 1995. The program consists of an
ordinance detailing what constitutes an illicit discharge and an illicit connection with
corresponding enforcement protocols. An illicit discharge takes the form of any non-
stormwater substance that has entered the stormwater conveyance system or is likely to
enter the stormwater conveyance system. An illicit connection is any connection which
allows the discharge of non-stormwater substances to the stormwater conveyance system.
Illicit discharges and illicit connections are identified through citizen complaints, reports
from City staff across all departments, dry weather screening, and stream walks. A team
of three staff are primarily dedicated to this program. Prevention measures include
educating City staff and the public through a variety of means and direct mailings to
categories of businesses, such as landscapers and restaurants, which have demonstrated
potential for discharges.
C.2 Best Management Practices
C.2.1 Develop/Implement Illicit Discharge Detection and Elimination Program
During this reporting period the Illicit Discharge and Elimination Program
achieved the following results.
Table C-1. Illicit Discharge and Elimination Program Achievements
Achievement Count
Water quality complaints investigated 80
Illicit discharges confirmed and eliminated* 70
Illicit connections confirmed and eliminated 48
NOVs issued 19
Civil penalties issued 0
Total amount of civil penalties issued $0
*Illicit discharge numbers are inclusive of illicit connection
Goals of the Illicit Discharge Detection and Elimination Program are to respond
to all water quality complaints within one business day, complete at least one
stream walk each year, and inspect high priority outfalls each year for dry weather
flows. The City is developing standard procedures for conducting stream walks,
outfall inspections, and record-keeping, ensuring goals for these activities are met
during the next reporting period.
Permit No. NCS000245 NPDES Stormwater Annual Report
October 1, 2017 - September 30, 2018
Page 8
C.2.2 Modify, as necessary, and maintain appropriate legal authorities
The Illicit Discharge Ordinance was established in 1995 by City Council and was
amended in February 2011. The ordinance was not revised during this reporting
period. The City is considering revising the ordinance to clarify enforcement
procedures for illicit discharges.
C.2.3 Complete the Development of a Storm Sewer System Base Map and
Inventory of Major MS4 Outfalls
First-pass inventory for the Raleigh corporate area and Raleigh’s extra-territorial
jurisdiction was completed during 2014-2015 reporting period, concluding the
development of the City’s Storm Sewer System Base Map.
C.2.4 Maintain an inventory of Major MS4 Outfalls that discharge to waters of
the State
The City maintains the stormwater infrastructure and MS4 outfall inventory
mapping by incorporating as-built data and completing field data collection and
verification on stormwater systems (second-pass inventory). Updates to the
inventory are being made to include stormwater infrastructure added to the system
from new development and redevelopment projects. Second-pass inventory
updates have begun in the Neuse River basin. Second-pass inventory updates have
been completed in the Sycamore Creek, Perry Creek and Toms Creek basins.
C.2.5 Inspection/detection program to detect dry weather flows at MS4 outfalls
Dry weather flow inspections are conducted per the procedures outlined in the
Engineering Services Department, Stormwater Management Division Standard
Procedure SW-100 Illicit Discharge Detection and Elimination. A new GIS-
based application was developed and implemented during this reporting period for
tracking and documenting dry weather outfall inspections. Major outfalls were
identified to target for inspection during the 2017-2018 reporting period. The
outfalls were prioritized based on:
• Impairment status of downstream water bodies
• Proximity to sanitary sewer lines and manholes
• Land-use
• Outfall pipe size
This prioritization strategy targeted outfalls susceptible to industrial and
commercial illicit discharges, potential connection to sanitary sewer lines through
pipe failures, dense residential development, and potential for a discharge to reach
surface waters. Figure C-1 shows prioritized outfalls for the City to be inspected
annually. Using this new application, 31 outfalls were inspected during this
reporting period.

Figure C-1. Priority Stormwater Outfalls
C.2.6 Employee Training
Approximately 237 City employees received training on illicit discharge detection
during this reporting period. This year, the City began transitioning from face-to-
face training to online training to improve coverage of training among City
departments and to facilitate tracking and recordkeeping of training activities.
C.2.7 Provide Public Education
Through the Public Education and Outreach Program, the City provides general
stormwater awareness education and an introduction to problems caused by illicit
discharges.
The City distributes educational brochures that are targeted to specific businesses
including automobile services, food services, landscaping services, and general
illicit discharge prevention. These brochures are provided to businesses when
first-time violations of the illicit discharge ordinance are observed by staff.
Information for preventing illicit discharges and reporting illicit discharges also is
provided on the City’s website.

C.2.8 Modify, as necessary, and maintain a public reporting mechanism
The City utilizes the Stormwater Management Division’s main telephone line as a
helpline. In 2016 the Stormwater Management Division initiated use of a
dedicated email address, IllegalDischarge@raleighnc.gov, as another helpline for
residents
During this reporting period, 80 helpline calls or emails from citizens were
received to report possible illicit discharges.
C.2.9 Established procedures to identify and eliminate failed septic system and
sanitary sewer overflows
When a sanitary sewer overflow or sewer leak is identified, and when a failed
septic system is located within the Raleigh City limits, procedures outlined in the
Engineering Services Department, Stormwater Management Division Standard
Procedure SW-100 Illicit Discharge Detection and Elimination are followed.

Section D: Construction Site Runoff Controls
D.1 Program Narrative
The City has had an active Construction Site Runoff Control Program (Sedimentation and
Erosion Control) since the 1970s. This program is delegated and overseen by the North
Carolina Department of Environmental Quality (DEQ). This program includes
ordinances, plan review, permitting, inspection, education, and enforcement activities.
The City receives and responds to calls and concerns from citizens on a regular basis.
SMAC reviews this program and makes recommendations to the City Council. All
related ordinance changes are noticed and subject to public hearing prior to adoption.
D.2 Best Management Practices
D.2.1 Erosion and Sediment Control Program
The Erosion and Sediment Control Program is delegated to the City by the DEQ
and is evaluated by the DEQ annually. The City has adopted an Erosion and
Sediment Control ordinance as part of its Development Regulations. This
ordinance meets the Land Quality Division’s minimum requirements.
For the reporting period program staffing included 1 Stormwater Development
Supervisor, 1 Stormwater Reviewer Supervisor, 4 Senior Stormwater Engineers, 2
Stormwater Engineers, 1 Stormwater Inspections Supervisor, 3 Regional
Stormwater Inspection Coordinators and 4 Stormwater Inspectors. Staffing levels
varied somewhat during this period as vacancies occurred and were filled. This
group handles all plan review and field inspection responsibilities for the
program.
D.2.2 Develop requirements for construction site operators
Requirements for construction are part of the City’s Development Regulations.
When plan approval and permits are obtained for any land disturbing activity over
12,000 square feet, construction site operators must coordinate with a Stormwater
Compliance Inspector. The site must be maintained per these regulations
throughout construction. Improper maintenance results in a notice of violation
and/or a civil penalty as outlined in the Development Regulations.
D.2.3 Educational and training materials for construction site operators
The City participates in annual training seminars for designers and contractors in
cooperation with the State and three other local municipalities. This training
provides the contractor an overview of each municipal sediment and erosion
control program and requirements are associated with each. There is no charge for
participating in this training seminar. This training has not been held during the
reporting period.

Page 12
D.2.4 Plan Reviews
Six Stormwater Engineers manage review and approval of stormwater plans for
new development sites.
Stormwater, erosion and sediment control, and floodplain plans for new
development are reviewed by Stormwater Engineers who report to a Senior
Stormwater Engineer. Reviews include calculations and details for proposed
stormwater devices. Senior Stormwater Engineers review larger projects and
projects where a stormwater device is shared between multiple owners.
Stormwater Engineers review smaller commercial projects and single-owner
projects. Approximately 859 development plans were reviewed during this
reporting period.
D.2.5 Public Information
Complaints received concerning active construction sites are logged into a
complaint database and assigned to a Stormwater Compliance Inspector. During
this reporting period, 445 calls regarding construction sites were received.
Response to the caller is generally made within one business day of the received
complaint. The complainant is contacted with the outcome when a resolution is
obtained.
D.2.6 Inspection and enforcement procedures
The stormwater inspections program is implemented by a Stormwater Inspector
Supervisor and a group of 7 Stormwater Compliance Inspectors. During the past
reporting period, the city was divided into two regions (as shown in Figure D-1)
and a team of three Stormwater Compliance Inspectors conducts inspections in
each region and coordinates with the regional Senior Stormwater Engineer, who
reviews and approves erosion and sediment control plans.
Permit No. NCS000245 NPDES Stormwater Annual Report
October 1, 2017 - September 30, 2018
Page 13
Figure D-1. Regional Stormwater Inspection Map
Approximately 8,432 construction site inspections were made during this
reporting period. Approximately 15 enforcement actions were initiated, including
1 fine for continuing violations.
Each team of Stormwater Compliance Inspectors works together to address
scheduled inspections, routine inspections, pre-construction meetings, plan
reviews and complaint calls throughout the region. Inspectors coordinate and
rotate through sites so that a “fresh” look is taken at each site and compliance is
consistently enforced. This team approach also allows the inspectors to provide
excellent customer service throughout their region even when a team member
may be out on leave.
Regional Coordinators serve as the primary point of contact, manage the regional
permit database, manage the routine inspection schedule, perform and document
inspections, attend pre-construction meetings, perform plan reviews, and answer
complaint calls. Senior Inspectors perform and document inspections, attend pre-

Page 14
construction meetings, perform plan reviews, answer complaint calls and serve as
a technical resource throughout the city, but primarily within their assigned
region. Field inspectors perform and document inspections, attend pre-
construction meetings, perform plan reviews, answer complaint calls and are
mentored up through the group by working closely with the other two team
members.

Section E: Post-Construction Site Runoff Controls
E.1 Program Narrative
The City’s Post-Construction Site Runoff Control Program remains in compliance with
its permit through ongoing compliance with the Neuse Nutrient Sensitive Waters
Management Strategy and Water Supply Watershed programs.
E.2 Post-Construction Stormwater Management Program Measures
The City implements the Neuse Nutrient Sensitive Waters Management Strategy [15A
NCAC 2B .0251] throughout the entire planning jurisdiction of the City of Raleigh.
Water Supply Watershed IV (WS-IV) Programs [15A NCAC 2H .0216] are implemented
within the Falls Lake watershed, Swift Creek watershed, and Richland Creek watershed.
The City’s Post-Construction Site Runoff Control Program is deemed compliant with the
implementation of the above-mentioned program measures.
The City has set up a private maintenance policy for owners of private properties with
BMPs. Every year, the private property owner must have a licensed professional
engineer or landscape architect certify the BMP is still functioning property and must
send that certification to the City. If these inspections are not made, then notification and
enforcement actions are undertaken. Fines in the amount of $20,000 were issued during
this reporting period. There were 323 failures to submit annual inspections during this
reporting period; these owners were sent “Not in Compliance” reports, and the failures
were remedied and confirmed by City staff.
E.3 Best Management Practices
E.3.1 Establish a program under the Post-Construction minimum measure to
control the sources of fecal coliform to the maximum extent practicable
When a sanitary sewer overflow or sewer leak is identified, and when a failed
septic system is located within the Raleigh City limits, procedures outlined in the
Engineering Services Department, Stormwater Management Division Standard
Procedure SW-100 Illicit Discharge Detection and Elimination are followed.
The following reports of leaks, overflows, or discharges by City staff were
investigated during this reporting period through the Illicit Discharge Detection
and Elimination program:
• 20 public agency sanitary sewer leaks or overflows
• 14 private sanitary sewer leaks or overflows
• 0 septic system discharges

Section F: Pollution Prevention and Good Housekeeping for
Municipal Operations
F.1 Program Narrative
Responsibility for good housekeeping and pollution prevention is delegated to each of the
departments that manage the various City operations. Stormwater staff assists these
departments through educational activities, site assessments, advice, assistance with
preparing stormwater pollution prevention plans, and implementing retrofits to capture
and treat runoff.
F.2 Best Management Practices
F.2.1 Develop an operation and maintenance program
Several departments within the City manage operation and maintenance programs
specific to individual facilities, operations, and the focus of their work. Each
department is responsible for developing and maintaining individual operation
and maintenance plans for their sites.
F.2.2 Develop Site Pollution Prevention Plan for Municipal Facilities
Each department is responsible for developing and maintaining Stormwater
Pollution Prevention Plans (SWPPPs) for each of their operations that may
contribute to stormwater pollution based on the template prepared by Stormwater
staff. As part of an internal City-wide audit in March of 2012 and an audit by
EPA in April 2012, each site’s SWPPP was reviewed and where necessary,
modifications implemented.
F.2.3 Inspection and evaluation of facilities, operations, and the MS4 system
and associated structural BMPs
Stormwater staff identified facilities likely to contribute to polluted runoff.
Because these facilities fall under several departments, regular inspection of the
facilities is the responsibility of the department that manages the facility.
Stormwater staff provides guidance and assistance regarding compliance.
F.2.4 Conduct staff training
During this reporting period, approximately 2,773 City employees received
training on good housekeeping.

Section H: Program to Monitor and Evaluate Storm Water
Discharges to Municipal Systems
H.1 Program Narrative
A program to monitor stormwater management and housekeeping at facilities that hold
Stormwater NPDES Industrial Permits was added to the City’s NPDES Stormwater MS4
Permit with its renewal in July 2007 and remains in the permit that was renewed in
March 2013. This new program was included in the City’s July 2008 Stormwater
Management Plan and remains in the plan updated in May 2015. The City maintains a
list of approximately 56 industrial facilities provided by the North Carolina Department
of Environmental Quality (DEQ). The City’s program provides for inspecting facilities
with Stormwater NPDES Industrial Permits at least every three years.
H.2 Best Management Practices
H.2.1 Maintain an inventory of industrial sites
The City maintains and updates a list of industrial facilities, as described in
Section H.1. During this reporting period, the City received no notifications from
DEQ of changes in Stormwater NPDES Industrial Permits within the area of the
City’s NPDES Stormwater MS4 Permit.
H.2.2 Inspection program
The City maintains protocols for reporting to DEQ issues of noncompliance with
Stormwater NPDES Industrial Permits. Illicit discharge staff and stormwater
inventory staff are trained in how to conduct inspections. In addition, the City
uses information from drainage system inventory inspections, observation by
stormwater inspectors, and follow up to citizen complaints to identify and address
problem facilities. The City inspected 26 sites during this reporting period; of
these, no permitted industrial facilities were found to be out of compliance.

Section I: Water Quality Assessment and Monitoring
I.1 Program Narrative
The original monitoring required as part of the NPDES Stormwater MS4 Permit
application included end-of-pipe sampling for various land uses. More recent monitoring
has moved away from end-of-pipe monitoring and is focused primarily on ambient
stream sampling. The City’s goal is to assess the status and changes in water quality of
water bodies in Raleigh. This is achieved through the application of the practices detailed
below.
I.2 Best Management Practices
I.2.1 Water Quality Assessment and Monitoring Plan
The City maintains a Water Quality Assessment and Monitoring Plan, updated
October 2016. This plan includes monitoring locations, monitoring schedule,
monitoring parameters, laboratory analytical methods, data evaluation and
assessment methods, and reporting protocols. The resulting data establish baseline
levels of water quality in each stream and provide an indication of the presence of
pollutants in stormwater originating in each watershed.
I.2.2 Water quality monitoring
Monitoring data were collected at the 18 monitoring sites identified in the Water
Quality Assessment and Monitoring Plan to characterize water quality conditions
within major watersheds in the City’s jurisdiction. Samples are collected four
times per year, resulting in four sampling dates during this reporting period:
January 24, 2018; March 20, 2018; June 12, 2018; and September 25, 2018.
Samples were analyzed for E. coli, total phosphorus, turbidity, total suspended
solids, total Kjeldahl nitrogen, nitrate + nitrite, ammonia nitrogen, copper, and
zinc by an NC DEQ certified laboratory. At each site, City staff recorded pH,
conductivity, dissolved oxygen, and temperature.
I.2.3 Revisions to the Water Quality Assessment and Monitoring Plan
The Water Quality Assessment and Monitoring Plan was updated during this
reporting period to reflect revised laboratory standard methods, detection limits,
sample volumes, and other analytical considerations that went into effect
September 30, 2015. These updates were incorporated into an updated Water
Quality Assessment and Monitoring Plan.
